Behavior
Harmless to humans, these lizards are known to run from potential threats. When disturbed, the Chuckwalla will gulp air, distend its body and wedge itself into a tight rock crevice. The Chuckwalla will inflate its body with air in order to entrench itself.
Males are seasonally and conditionally territorial; an abundance of resources tends to create a hierarchy based on size, with one large male dominating the area's smaller males. Chuckwallas use a combination of colour and physical displays, namely "push ups", head-hobbing, and gaping of the mouth to communicate and defend their territory (see animal communication).
Chuckwallas are diurnal animals and as they are exothermic, spend much of their mornings and winter days basking. These lizards are well adapted to desert conditions; they are active at temperatures of up to 102°F (39°C). Chuckwallas brumate during cooler months and emerge in February.
Mating occurs from April to July, with 5-16 eggs laid between June and August. The eggs hatch in late September.

Famous quotes containing the word behavior:
“There is a parallel between the twos and the tens. Tens are trying to test their abilities again, sizing up and experimenting to discover how to fit in. They don’t mean everything they do and say. They are just testing. . . . Take a good deal of your daughter’s behavior with a grain of salt. Try to handle the really outrageous as matter-of-factly as you would a mistake in grammar or spelling.”
—Stella Chess (20th century)
“Excessive attention, even if it’s negative, is such a powerful “reward” to a child that it actually reinforces the undesirable behavior. You need to learn restraint, to respond to far fewer situations, to ask yourself questions like, “Is this really important?” “Could I let this behavior go?” “What would happen if I just wait?” “Could I lose by doing nothing?””
—Stanley Turecki (20th century)
“To be told that our child’s behavior is “normal” offers little solace when our feelings are badly hurt, or when we worry that his actions are harmful at the moment or may be injurious to his future. It does not help me as a parent nor lessen my worries when my child drives carelessly, even dangerously, if I am told that this is “normal” behavior for children of his age. I’d much prefer him to deviate from the norm and be a cautious driver!”
—Bruno Bettelheim (20th century)
